Nathan has always guarded a monumental secret, even from his closest friend, Victor. He isn’t just any sixth-grader; Nathan’s family hails from another planet, and he’s part of an intricate experiment designed to help him assimilate into human society.

But the experiment is faltering. Fellow participants, including Nathan’s crush, Izzy, are vanishing without a trace. When his family is summoned back to the mothership, Nathan begins to doubt everything he’s ever known about his identity and purpose on Earth.

Can Nathan, Victor, and Izzy unravel the truth behind the experiment?

The Experiment is a thrilling adventure that delves into the universal quest for self-discovery, the power of change, and the enduring significance of friendship, all set against a backdrop of interstellar intrigue.
